A constant force `3hati +4hatj-5hatk` acts on a particle at `hati + 2hatj +2hatk` and moves it to a point on the `z`-axis which is `3` units from origin, the work done is

A constant force of (2hati+3hatj+5hatk) N produces a displacement of (3hati+2hatj+2hatk) m. Then work done is

A constant force of (2hati+3hatj+5hatk) N produces a displacement of (3hati+2hatj+2hatk) m. Then work done is

A force (hati-2hatj+3hatk) acts on a particle of positive vector (3hati+2hatj+hatk) . Calculat the torque acting on the particle.

A force (hati-2hatj+3hatk) acts on a particle of position vector (3hati+2hatj+hatk) . Calculate the torque acting on the particle.

A particle is acted upon by constant forces 4hati +hatj - 3hatk and 3hati + hatj -hatk which displace it from a point hati + 2hatj + 3hatk to the point 5hati + 4hatj + hatk . The work done in standard units by the forces is given by:

Torque of a force F = -3hati + hatj +5hatk acting at the point r = 7hati+3hatj+hatk is

If the constant forces 2hati-5hatj+6hatk and -hati+2hatj-hatk act on a particle due to which it is displaced from a point A (4,-3,-2) to a point B (6,1,-3), then the work done by the forces is

A particle acted by constant forces 4 hati + hatj - 3 hatk and 3 hati + hatj - ahtk is displaced from the point hati + 2 hatj + 3 hatk to the point 5 hati + 4 hatj + hatk. The total work done by the forces is :

If the constant forces 2hati-5hatj+6hatkand-hati+2hatj-hatk act on a particle due to which it is displaced from a point A (4,-3,-2) to a point B(6,1,-3) , then the work done by the forces is a)10 unit b) -10 unit c)9 unit d)None of these
